What causes puffy eyes? Fluids get trapped in the tissues under the eyes. Usually the eyes are puffiest when you awake. Puffy eyes can also be a sign of sinus and allergy problems. AAAAI says allergic conjunctivitis
affects about 22 million people in the
USA.

Neat site regarding allergy alerts etc-Hangovers can also produce puffy eyes. At first the alcohol lowers the anti-diuretic hormone (ADH) but as the hangover gets into full force, ADH increases again and helps the body to retain fluid.Drug induced hypothyroidism(such as lithium) can also cause puffy eyes.
